traceinfo & cache invalidation timeouts

We experiencing the flood of traceinfo entries for cache invalidation
due to timeout as described in the QNX knowledgebase. We can use fdisk
info to verify that the flash drive is reporting itself as removable.
However, when we try to use scsi_util to lock the drive, we receive
several lines of complaints starting with lock(failed) and ending with
INVALID COMMAND. The flash disk is under Fsys.eide 4.24M dated 5-13-98,
and scsi_util is dated 8-12-96. We are, of course, logged in as root.

Any advice on how to stop the trace entries will be appreciated.
